Very big thanks to all who replied to my earlier message! If I understand right, RAID is bad on access time and if I want fast proxy I should buy e.g. WD Raptor 10000rpm. How does RAID slows down the disks speed if I have e.g. 4 pcs WD Raptor 10000rpm 74Gb on hardware or software RAID? Or is it realy better to have 4 pcs WD Raptor 10000rpm without RAID? Or is the gain from RAID so little it's not worth it? What would be the best amount of storage to cache 300 user network. which is most important when not using RAID: The amount of disk space or the amount of disks.
